What can a 35$ microcomputer do? Such a stupid question

What can a 35$ microcomputer do? Such a stupid question

The right question should be what a 35$ microcomputer can’t do.

35$ enough to buy you a meal, also can buy you a Raspberry Pi and  make little something out of it.

Raspberry Pi is a microcomputer. Although the various components are exposed and small, all the basic functions of the computer are available. The key thing is that it only sells for $35!

Raspberry Pi, which was officially released in 2012, is very suitable for DIY small creations and small hardware because of its low power consumption, mobile portability, and GPIO (general-purpose input and output). Today, the Raspberry Pi has become a symbolic presence in the geek circle and the DIY circle.

Recently, the Raspberry Pi has been updated to the fourth generation. The performance has been improved by nearly 3 times, the interface has been fully upgraded, equipped with 4G large memory version, 4K dual screen support, operating system update, and machine learning ability has been strengthened.

The DIY circle has once again ushered in a carnival, and the promotion of the Raspberry Pi 4 means more possibilities for creativity. In fact, the ideas that the Raspberry Pi community has evoked in the past are amazing enough.

Low cost can also make robots

Because Raspberry Pi is equipped with a universal I/O port on the board, it can control lights, switches and motors, and can interact with other boards, thus promoting the birth of a large number of Raspberry Pi-driven robots, and even a global Raspberry Pi Robot Competition Pi Wars.

Based on the Raspberry Pi, a hexapod robot is the most common operation:

The original intention of the Raspberry Pi design is for education, and there are many robot projects that motivate young people to be passionate about machinery and programming.

Mini Robotic Arm, MeArm Pi uses Raspberry Pi as a manipulator that allows the robotic arm to be programmed in a variety of programming languages and then controlled via the onboard joystick.

This mini robotic arm can complete some very fine tasks.

On the Nybble, a robotic cat for children’s education, the Raspberry Pi is used as a “brain”, not only for the task of sending action commands to Arduino (another microcontroller), but also for simulating cats’ unpredictable emotions.

Nybble’s body is made up of various wooden components. It is trained by algorithms and behaves like a real cat. It not only runs and jumps, but also has good balance.

It can stand up when being pushed down.

It can even do pull-ups… (The cat doesn’t seem to have this skill?)

Does it look like a Boston Dynamics robot? Unlike the expensive Boston-powered robots, Nybble for children’s education costs just over RMB 1,700 due to the use of cheap hardware such as the Raspberry Pi. This project has already completed the crowdfunding target in the crowdfunding platform indiegogo, and now it has entered the delivery phase.

Explosive modified childhood game machine

Since it is to play with the Raspberry Pi, it is definitely a game machine.

Adafruit, the open source hardware company, uses the Raspberry Pi as the core, and 3D printing to make the shell, and then adds some components to DIY a Game Boy.

 Raspberry Pi Game Boy can play Super Mario. Pic cr. Adafruit.

If the Game Boy game is not enough for you, RetroPie will definitely satisfy you.

RetroPie is an open source game simulator built on Raspbian, an operating system designed specifically for the Raspberry Pi. It integrates Nintendo Red and White, GameBoy, SNES and other game systems to make the Raspberry Pi a Nostalgic game center with tens of thousands of games in history.

If you’re hardcore enough, you can also set up an arcade at home based on RetroPie like this buddy.

Even, you can use the Raspberry Pi to make a Switch console. of course. Nintendo won’t like this idea.

Self-made Polaroid

Polaroids with Raspberry Pi is also an option that many DIY players like to try.

Raspberry Pi + Digital Camera Module + Thermal Printer, the material needed for a Polaroid is not complicated.

Raspberry Pi that can fly to the sky

To say the most hardcore, it should be using hot air balloons to raise the Raspberry Pi to near space and take photos of high-altitude.

When Dave Akerman, a British high-altitude hot air balloon enthusiast, received the first generation of Raspberry Pi in 2012, he used it as a flying computer and sent it to nearly 40,000 meters of near space.

Dave used to use other microcomputers to fly high-altitude hot air balloons before, but they couldn’t take pictures, and the Raspberry Pi had a USB interface and could be connected to the camera. The following are photos taken by the Raspberry Pi connected camera. Although not very clear, they are all returned in real time.

Miraculously, this Raspberry Pi that reached 40,000 meters of near-space was not destroyed by extreme temperatures, and it could be recycled and reused. Later, he used the Raspberry Pi and high-altitude hot air balloons to track cars and make video streams.

There are so many creations around the Raspberry Pi, and the article shows just a glimpse. Hardcore hardware media Tom’s Hardware once said, don’t ask what the Raspberry Pi can do for you, but ask what you can do with it?
